The Maxpedition Proteus Versipack is incredibly well built. It's waterproof, the carrying handle makes it really easy to either carry or adjust around your waist.
If I had to say there was an issue with it, it would be that the belt tighteners slips too easily. When I grab the pack by the plastic belt buckles so I can clip them around my waist, the weight of the pack pulls the belt tighteners and the belt tightness changes as a result.
An attachment to 'retain' the belt tightness would be helpful in this regard.
In addition, I have difficulty finding out which attachment tietacs or accessories I should be getting for the pack. I can see that the 5" tietacs are recommended, but it's not clear it those are to attach the Versipack to a backpack, or to attach accessories to the Versipack. Because I do not have a local distributor it's difficult to find out myself at a shop and I don't want to order an item online, have it delivered and find out it isn't what I need.
Pros: Lots of room, durable, hard wearing, carrying handle
Cons: belt adjustment slips, not easy to see what compatible attachment accessories are
